The DUI Law in Maryland
In Maryland the offense is DUI, and the limit is 0.08; driving while impaired (DWI) is charged from 0.07.
Driving in Maryland is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Motor Vehicle Administration, separately from the criminal case.
Who Makes DUI Arrests in Rockville
The Montgomery County Sheriff's Office, the Montgomery County Police Department and the agency that reports for Rockville (filed by the FBI as Rockville Police Department) make the DUI arrests in and around Rockville.
The FBI's agency list also places these agencies in Montgomery County: the Montgomery County Maryland-National Capital Park Police (other agency); the Montgomery County State Police (state police); the Montgomery County State Police makes the arrests on the state highways.

The License Case
The court case is only half the record. The Motor Vehicle Administration runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Maryland Motor Vehicle Administration keeps the driving record the conviction goes on.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the Maryland Public Information Act.
- The court file: from the District Court, kept by the Clerk of the Circuit Court.
- The driving record: from the Maryland Motor Vehicle Administration.
